KNACRO RS232 to TTL Serial Port Module Bidirectional Transceiver Compatible with 3.3V 5V Hardware Automatic Flow Control with Over-Voltage Protection for Arduino

#ad
KNACRO #ad - Rs232 communication chip: sp3232. Operating voltage: 3V-5V; with four bidirectional transient suppression diode signal voltage protection. Rs232 female to ttl serial port bidirectional transceiver module, write router firmware, NXP microcontroller Download.

This module contains over-voltage protection circuit to better protect your computer and equipment. This module contains hard flow control, causing chip oscillation and introducing high-frequency interference and increasing power consumption, and the TTL side of the module RTS signal is not dangling, is set to enable bidirectional transceiver function by default.

Prevent sp3232 from floating in some pins, thus affecting the normal operation of the entire chip. Db9 interface Type: Female. Can also be used for other purposes, for sst, gps signal reading and other functions, such as hard disk repair, STC, but requires users to have a certain level of technology can be achieved.
